Abstract: Insulation is a vital component in the construction industry, notably in this study, glass wool. Maximizing the hydrothermal performance of glass wool is key when dealing with water vapor, humidity and permeability. Although insulation does not generally come in contact with liquids, it is important to consider all outcomes, with likelihood of accidents occurring and the varying levels of workmanship. The hot disk transient technique was employed to thermally characterize glass wool and it was determined to be a function of water. When exposed to water, the thermal conductivity of glass wool was raised by a factor of two. This study alluded to the usefulness of the hot disk method when assigning thermal properties to insulating materials.
